Tywin later criticizes Arya's pronunciation of "My lord." He says that she sounds high born but Arya counters that her mother served as a handmaid to Lady Dustin for many years and taught her how to speak properly.[2]

Brandon Stark was fostered during his youth at Barrowton by House Dustin and Barbrey Ryswell was besotted by him. She hoped to marry him, but this was dashed when he was betrothed to Catelyn Tully. Barbrey instead was left to marry Lord William Dustin, whose lands are on the eastern border of House Ryswell's. Following William's death at the end of the rebellion, it isn't clear if he had any heirs, as Lady Barbrey appears to rule Barrowton in his name. As a result, Lady Barbrey leads House Dustin to closely follow neighboring House Ryswell in political decisions, as its current lord, Rodrik, is her own father.

Lady Dustin holds a grudge against Eddard Stark for not bringing her husband's bones north with him so she could bury him at his ancestral home.
